Quote - what i found interesting is that the glass shader still exhibits reflection and refraction by a
posersurface, even though "visible in raytracing" is unchecked for the glass object.  in addition,
my initial attempt at a render of the glass-fronted box with IDL IC at 100 (GIMaxError=0)
appears to allow lite from the hdri on the envsphere into the box (thru the glass front) but it's
the slowest render since GI/poser 7, hence I hadda terminate.

this is great. and it is good for us.
